Specification of Letters Patent No. 649, dated March 21, 1838.

To all whom 'it may concern.'

Be it known that I, WALTER HUNT, of the city, county, and State of New York, have invented a new and useful mode of constructing or forming flat, coiled, or spiral wire springs, adapted to various purposes of dress, such as pantaloonstraps, vest-backs, Suspenders, belts, Sac., and thatthe following is a faithful description thereof.

In forming springs for the above purposes I use about No. Q0 steel wire (other metals may be used) which by hand in a turning lathe or otherwise I wind spirally around a flat steel arbor or blade of suitable dimensions, (a piece of thin, inch hoop iron may answer the purpose) upon this the wire 1s wound, the turns about inch apart, see

p Figure No. 1 1n the annexed drawingarbor A, spring B. Thus far there is no novelty in the spring or mode of forming it; I neXt proceed to Withdraw the arbor or mandrel, and with pliers or otherwise, I form hooks or tongues of and upon the projecting ends of the wire of which the spring is composed. See Fig.' 2, C C. In this last forming of the tongues upon the opposite ends of the spring, consists the novelty and utility of my invention in as much as it aords the most simple and advantageous means of attaching the spring to straps, &c., in such manner that it may act by extension and perform the twofold oiice of spring and buckle aseXhibited in'Figs.A 3 and 4 which represent an inner and outside View of a strap for the bottom of pantaloons composed of one long and two shortstraps see D and E E. The ends of which pass through two springs F ig. 2, and receive the tongues or hooks VC C in graduating holes punched in the ends of the long center strap D at F F F F. The same mode of attaching is applicable to belts, Suspenders, &c;

What I claim and desire to secure by Letters Patent is-
